Umenyiora, who missed all of last season with a knee injury, attended meetings in the morning at the team's headquarters. However, he left unexpectedly without talking to Coughlin and didn't return for the workout.
Umenyiora skipped practice after getting into a dispute with new defensive coordinator Bill Sheridan. Sheridan, the former linebackers coach who replaced Steve Spagnuolo as coordinator, reportedly criticized Umenyiora for making a mistake in Saturday's game against the Jets.
